Molecular evidence for genetic subdivision of Antarctic krill (Euphausia superba Dana) populations.
Antarctic krill (Euphausia superba Dana) is a key species in the Antarctic food web and occurs on a circumcontinental scale. Population genetic structure of this species was investigated by sequence analysis of the ND1 mitochondrial gene in four population samples collected at different geographical...
